Schulz said his stepmother, Jean Schulz, the cartoonist’s 78-year-old widow, was able to evacuate the home before it was engulfed by flames around 2:00 a.m. Monday.

“It’s the house he died in. All of their memorabilia and everything is all gone,” Monte Schulz said.

The Schulzes built the California split-level home in the 1970s, the AP reported. The cartoonist lived there until his death in 2000.

Most of Schulz's original "Peanuts" comic strips, artwork and memorabilia are housed at the Charles M. Schulz Museum and Research Center, which is also in Santa Rosa but has been, so far, untouched by the blazes.
